The Zalman CNPS8000 is pegged as a low noise, low profile heatsink ideal for compact computers, largely because it stands just 63mm tall. Aluminum fins, four sintered metal wick copper heatpipes and a forged copper base form the basis of what is called the CNPS8000 heatsink. A 90mm fan spins quietly at the center of it all, and with Zalman's Fanmate 2 fan speed controller noise can be reduced even further for true silent cooling. The Zalman CNPS8000 heatsink is compatible with all current AMD Athlon64 processors (754/939/940), and in particular the just introduced 940-pin processor socket AM2 processor and its revised 'M2' heatsink retention frame.
